The Morphologies of the Small Magellanic Cloud [PDF]

The Astrophysical Journal, 2000
We compare the distribution of stars of different spectral types, and hence mean age, within the central SMC and find that the asymmetric structures are almost exclusively composed of young main sequence stars. Because of the relative lack of older stars

N-body Simulations of the Small Magellanic Cloud and the Magellanic Stream [PDF]

Monthly Notices of the Royal Astronomical Society, 1995
An extensive set of N-body simulations has been carried out on the gravitational interaction of the Small Magellanic Cloud (SMC) with the Galaxy and the Large Magellanic Cloud (LMC). The SMC is assumed to have been a barred galaxy with a disc-to-halo mass ratio of unity before interaction and modelled by a large number of self-gravitating particles ...

The Structure of the Small Magellanic Cloud [PDF]

The Astronomical Journal, 1961
In the infrared passband λλ 7000-7600 (103a-U emulsion plus RG8 filter) the 8-inch Schmidt shows the Small Cloud as a quite elliptical patch with some internal structure (Plate I). It is natural to ask whether the Small Cloud is, in fact, a complex system with one component having the essential characteristics of an elliptical galaxy.

Evolution of the Small Magellanic Cloud [PDF]

, 2007
Based on the results of N-body simulations on the last 2.5 Gyr evolution of the Large and Small Magellanic Clouds (LMC and SMC, respectively) interacting with the Galaxy, we firstly show when and where the leading arms (LAs) of the Magellanic stream (MS)

Planetary Nebulae in the Small Magellanic Cloud [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We analyse the planetary nebulae (PNe) population of the Small Magellanic Cloud (SMC), based on evolutionary models of stars with metallicities in the range $10^{-3} \leq Z \leq 4\times 10^{-3}$ and mass $0.9 M\odot < M < 8M\odot$, evolved through the ...

Tiny-Scale Molecular Structures in the Magellanic Clouds (Part 1) [PDF]

Astron.Astrophys. 422 (2004) 483-504, 2004
We report on the {\small FUSE} detections of the HD and CO molecules {\bf on the lines of sight towards three Large Magellanic stars}: Sk $-$67D05, Sk $-$68D135, and Sk $-$69D246. HD is also detected for the first time {\bf on the lines of sight towards two Small Magellanic Cloud stars}: AV 95 and Sk 159.

Infrared Dark Clouds in the Small Magellanic Cloud? [PDF]

The Astronomical Journal, 2009
We have applied the unsharp-masking technique to the 24 $\mu$m image of the Small Magellanic Cloud (SMC), obtained with the Spitzer Space Telescope, to search for high-extinction regions.

Low-excitation blobs in the Magellanic Clouds [PDF]

, 2006
Aims : We study an unknown, or very poorly known, interstellar HII component in the Magellanic Clouds. This is the first study ever devoted to this class of objects, which we call Low-excitation blobs (LEBs). Methods : We used low-dispersion spectroscopy carried out at ESO to obtain emission line intensities of Ha, Hb, and [OIII] (4959+5007) for 15 ...

INTEGRAL observations of the Small Magellanic Cloud [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
The first INTEGRAL observations of the Small Magellanic Cloud (carried out in 2003) are reported in which two sources are clearly detected. The first source, SMC X-1, shows a hard X-ray eclipse and measurements of its pulse period indicate a continuation

The chemical composition of the Small Magellanic Cloud [PDF]

Astronomische Nachrichten, 2013
The Small Magellanic Cloud is a close, irregular galaxy that has experienced a complex star formation history due to the strong interactions occurred both with the Large Magellanic Cloud and the Galaxy. Despite its importance, the chemical composition of its stellar populations older than 1-2 Gyr is still poorly investigated.
